By preventing the ejected liquid of (1) from converging in one place, it is possible to prevent the interference and turbulence of the fluid in the converging portion, and prevent the flow velocity of the ejected liquid from decreasing. Therefore, it is possible to prevent a decrease in the suction force of the ejector due to a decrease in the flow velocity.

る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiment will be described in detail. FIG. 1 shows an overall configuration diagram of the liquid ejector. A nozzle portion 2 is provided at an end of an inlet 1 for a liquid as a driving fluid. The nozzle portion 2 is formed by a cylindrical member 5 penetrating the fine holes 3 and 4. A suction chamber 6 is formed around the nozzle portion 2 to provide a suction passage 7 through which gas passes. A diffuser portion 8 is connected to the right side of the suction chamber 6.
